Abstract
We have studied the competition between neutral atom evaporation and asymmetric fission as fragmentation channels for doubly charged alkali-metal clusters. We have used an Extended Thomas-Fermi (ETF) method and the jellium model to compute the evaporation energy and the completely asymmetric fission barrier height in the case of Na 2+n . Preliminary calculations are also presented for the symmetric fission channel.KeywordsAtom EvaporationCoulomb ExplosionFission BarrierJellium ModelCharged FragmentThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
